IMPROVEMENT IN GRAlN-B INDERS.

Specification forming part of Letters Patent No. 1 11,069, dated January17, 1871.

To all whom it may concern:

Be it known that I, SYLVANUS D. LOCKE, of J anesville, in the county ofltock and State of Wisconsin, have invented a new and useful Improvementin Grain-Binders; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, in Which- Figure 1 is a perspective view of abind-' ing-head.- Fig. '2 is-a plan of the entrance Fig. 3 is a transthe cutter andgriper at the moment when the twisters commence to move.Fig. 6 is a side elevation'of the twisting mechanism, including one jawof the cutter and griper at the time when the twisters are revolving.Fig.7 is a diagram to show the general connect-ion of the devices hereindescribed with the operating machinery. Fig. 8 is a plan of the tableend of the binding-arm.

My invention relates to that class of grainbinders which have a rotatingarm to carry the binding material; and it consists, first, in theholding and twisting device, composed of two pinions independentlyrotated on the same axis, and holding the ends of the wire or cordbetween them; second, in the'outer shield to cover and protect the.twisters, and

conduct the binding material properly thereto; third, in the arrangementand construction of the cutting andgripiug jaws; fourth, the arrangementof thejcamways, by means of which the cutter is operated; fifth, the

guard-spring to prevent the lever of the cutter from 'entangling thegrain; sixth, the guard-sprin g to prevent grain from entan glm g in thetwisters'; seventh, the retaining springlatch, which receives andretains one end of to by arake, which separates the grain into gavgls,by an endless apron, or by other suitable mechanism. ;The plan which Iprefer, however, is represented and described in my patent dated 30thAugust, 1870. The general plan and method of moving the devices whichcarry the binding material and secure the sheaf are also shun n anddescribed in my said patent, to which reference is hereby made for thepurpose of explaining the'general manner of connecting the devicesherein described with the harvesting-machine and its prime motors.

The objects to be attained by my-invention are, first, to carry thebinding-wire around the gavel; second, to'unit-e the ends of said wireby twisting; third, to sever the wire between the twist and a pointwhere it is seized and held bythe mechanism, so thatafresh portion maybe drawn out and carried around another gavel at the next revolntionoithe ma chine. The second and third motions must be nearly or quitesimultaneous.

That others may fully understand. this invention I will particularlydescribe it.

The general connection of the devices herein described, with theharvesting-machine are shown in Fig. 7, wherein the arm A rotates aboutthe axis B, and carries in its rotation the head G,'which contains themechanism for seizing, holding, cutting, and ,twisting the binding-wire.D represents the gavel-tray, in which the, grain is deposited by theendless apron, or other moving mechanism. E is a compressor, and'F is anarm, which acts as a compressor in connection with the arm E, and alsoserves to force the binding-wire on one side into the twistingmechanism. These several parts with their arrangement and joint actionare fully shown and described in my patent hereinbefore referred to,and, therefore, no further 'descri pt-ion of them is required in thisplace. The head 0 in its general form resembles a shuttle; At its rearend it is rigidly secured to the arm A. The end of the arm A is bentdownward, and flattened at a, to form a table, upon which to mount thetwisting-pinions G H and the cutt'ting and holding jaws I J. The shieldK, \vhichcovers and protects the outer side of the twisting mechanism,.is also attached to the table a, and in practice the part J of theholding-jaws is 2 nuance formed with, and a part of. said shield, thoughcutting and griping jawJ maybe separately constructed and attached tothe shield, or to the table a, as preferred; The spring L closes andholds thejaw-I when the same has been opened by the operating-cam U, andagain released therefrom.

Beneath the gavel-tray D guide-box M is located, to guide. the head 0 inthat part of its revolution, and to insure the proper meeting of theends of the binding-wire. It also serves as a convenient attachment forthe cams U W, which operate the cutter, the guide-roller N for thebinding-wire, and for toothed rack, which rotates the twisters.

The binding-wire is coiled upon a reel located at any convenient placeupon the machine; but preferably just below the elevated part of theendless apron, upon which the grain is conveyed to the binder. When thehead 0 is commencing its revolution the binding-wire b from the reelpasses under the guide-roller N, and is griped be-' tween the jaws I J,as shown in Figs. 2 and 6. The forward motion of the-head 0 draws thewire b out from the reel, and, as shown in Fig. 7, carries it around thegavel. If there were no obstruction in the gavel-tray the wire b would,during the first half of its revolution,

describe a straight line from the roller N to the head 0; but thepresence of grain in the gavel-tray will causethe wire to assume acurved line. When the head (3 has passed over about three-fourths of itsrevolution from the roller-N the. wire b will have been gradually drawnover the head 0, and behind the rear edge of the shield K, until itassumes the position shown at 1), Figs. '1, 2, 5, 7, and the latch-spring 0 will then retain it in that posi: tion as the head G descends towardits startin g-point.

When thejaws IJ are opened to receive i the wire the end which wasgriped at first is released but it is, for a moment, held in place bythe hook formed around the pin 1?, as

shown in Fig. 5. The pin P is set in the jaw J, and projects-into acavity made for that purpose in the jaw 1, so that the end of said pinis not uncovered when the jaws are opened.

When the head 0 has completed-its circuit the wire b, as shown in Fig.5, passes around the pin P upward between the rear teeth of the pinionsG H, over the latch-spring O, and thence around the gavel, and againdown ward between the front teeth of said pinions, and

between the cutting and griping jaws I J. The further forward motion ofthe head 0 causes the jaws I' J to close and sever the wire 12 and thepinions G H at the same instant to rotate and twist the ends together,as shown in Fig. 6. The sheaf is then thrown out by the continuedmovement of the head 0 and action of the compressors E F. The pinions GH are arranged to engage with the alternating teeth of the racks Q, B,so that when they come fully in mesh with said racks their teeth willalternate, as .shown in Figs. 1, 2. 5, 6, and the wire is therefore bentand crimped between the two pinions,.as shown in Fig. 2. By this meansthe twisting-pinionsare caused to hold the ends of the wire after thegripingjaws have released it, and while the twist is being made.

The contiguous surfaces of the'pinions G H are grooved, or set so as tobe slightly separated, as shown in- Figs. 2, 5, 6, and the forward edgesof the leaves of the pinions are rounded, so that the wire will not becut or broken.

The racks Q R are made suificiently long to give the required number ofturns to the twist, and when the pinionsGr H have passed out ofengagement with said racks the wire will be released, and the sheaf willbe discharged.

The above comprises a general description of the mechanism and resultsaccomplished by this invention, and it only remains to describe someaccessories which are convenient to secure the regular and: uniformaction of the several parts.

The racks Q R are secured to the side of the box M, whichis curved inthe are described by the head 0 in its revolution. At the bottom of thebox M there are parallel ribs S T, the former of which serves as a guidefor the head Gas it passes under the gavel-tray, and the cam V is placedat the end of the box to open the jaw I at the moment when the end ofthe wire is to be released, and the reel part to be received, griped,and severed. The jaw I is prolonged backward, and the extreme end isturned downward to form a stud, d, which engages withthe cam [let theproper mo ment. When the stud d'passes the cam U the spring L will causethe jaws to close again, but the cam W is placed at the end of thecam-rib T, to force the jaws together by a positive motion. The rib Tand spring L will hold the jaws closed during the remainder of therevolution of the head C. While the head 0 is passing through the box.Mthe lateral friction will be received by the twistingpinions G H on theoneside, and. by the friction-roller e on the other side, while the pro-.jection f of the shield K will slide upon the guide-rib S. Thespring-guard g is placed on the jaw-lever I to prevent the-grain from entangling withthe stud d. This spring is only strong enough to resist thepressure of the grain, and yields readily to the rib T when the head 0enters the guide-box M. For the same purpose a guard-spring, h, isplaced to close the space between the point of the headv G and theshield K. This spring will yield readily to permit the wire I) to pass,but has sufiicient strength toprevent the'admission of grain into thetwisting mechanism.

It is evident that the mechanism for producingthe-several movementsdescribed above must be so adjusted as to secure the proper timing ofthose movements. Supposing the head 0 to have carried the binding Wire Inearly around the guide-box M, the point of the head 0 will first passthe binding-wire near the guide-roller N, and said wire will press backthe spring 7:. and enter between the head G and the shield K. The armsEF will, at the same time, descend and compress the gavel, and the arm Fwill, at the same time, press the wire hack into the. forward teeth ofthe twisting-pinions, as shown in Fig. 5. This may be termed the firststage.

The stud d engages with the cam U, and the jaws are thereby opened torelease the end of the binding-wire, and receive the part to be severedand griped. While the stud d is in engagement with the cam U the pinionsG H engage with the teeth of the racks Q It, and the teeth of'thepinions are thereby caused to assume the positions shown in Figs. 1, 2,5, 6,

with the teeth of one opposite to the space of the other, and with thewire crimped between them. The further movement of the head 0 rotatesthe pinions and withdraws the wire end around the pin P, and frombetween the 'jaws I J, and into the notches u y. This may be termed thesecond stage.

An instant subsequent to the engagement of the pinions and racks, and assoon as the end of the wire is withdrawn around the pin P, the stud dengages with the cam W, and the wire is griped between the jaws I J, andsevered at the same instant. This may be termed the third stage.

As the head 0 continues to move forward the pinions G H are revolved,and the hinding-wire is twisted, as shown in Fig. 6'. This may be termedthe fourth stage.

When the head 0 passes out of the box M the arm F will recede, thepinions will assume their first positions, with their teeth oppositeeach other, and the sheaf will be discharged.

It is obvious that, to secure and maintain themeoessary accurateadjustment of the several parts, they must all be rigidly secured inproper position at the place of manufacture.

Hence the necessity of securing the severalcams, the racks and theguide-roller. to the same foundation, and the guide-box M serves thatpurpose.

apparatus to the harvesting-machine, and they proper timing of theseveral movements will not be disturbed.

The pinions G H are shown as centered upon the bolt t,- hut it isevident that the same results would be attained if they were mounted ina shell, so that the hearing would be upon the ends of the teeth, thoughthat arrangement is considered less perfect than the one shown.
